Altitude derating
400/480 V drives: In altitudes 1000 … 4000 m (3281 … 13123 ft) above sea level, the
derating is 1% for every 100 m (328 ft). In addition:
•
A maximum altitude of 4000 m (13123 ft) is permitted for these earthing systems:
TN-S, TT. A maximum altitude of 2000 m (6562 ft) is permitted for these earthing
systems: corner-grounded delta, IT (ungrounded).
•
Above 2000 m (6562 ft), the maximum permitted voltage for the relay output RO1
decreases. At 4000 m (13123 ft), it is 30 V.
•
Above 2000 m (6562 ft), the maximum permitted potential difference between the
adjacent relays of the BREL-01 relay extension module (L511) decreases.
At 4000 m (13123 ft), it is 30 V.
To calculate the derated output current, multiply the current in the ratings table with the
derating factor
k
, which for
x
meters or feet is:

Switching frequency derating
Derating the drive output current is necessary when using high minimum switching
frequencies. If you change parameter
